\usage{
plotuScree(Eigenvalue, x = Eigenvalue, model = "components",

...)
}
\arguments{
\item{Eigenvalue}{depreciated parameter: eigenvalues to analyse (not used if
x is used, recommended)}
\item{x}{numeric: a \code{vector} of eigenvalues, a \code{matrix} of
correlations or of covariances or a \code{data.frame} of data}
\item{model}{character: \code{"components"} or \code{"factors"}}
\item{ylab}{character: label of the y axis (default is \code{Eigenvalue})}
\item{xlab}{character: label of the x axis (default is \code{Component})}
\item{main}{character: title of the plot (default is \code{Scree Plot})}
\item{...}{variable: additionnal parameters to give to the
\code{eigenComputes} function}
}
\value{
Nothing returned with this function.
